In mathematics, you don't understand things. You just get used to them.
90% of mathematicians do not understand 90% of currently published mathematics.
I am willing to wager that over 75% of the new words that appeared were nothing more than spelling errors that caught on.

Hi nurshodiq;

I think that

is the only solution.

Since it factors into:

and both of those terms are greater than 1 for all

must consist of 2 or more primes or two or more composites so

cannot be prime
